fer mechanism for the registering devices thereof. The mechanism shown in the accompanying drawings is also shown and described in applicants copending application for Letters Patent of the United States, Serial No. 792,869, filed October 1st, 1913. Only so much of the machine disclosed in said copending application as is necessary to the understanding of the features of the invention claimed herein is shown and described in the present application and for a complete description of the machine reference may be had to said copending application.

The principal object of this invention is to provide a simple and efficient transfer mechanism, one so constructed as to require 4 less time for effecting transfers than is required in the usual forms of transfer mechanism. The saving of time is of considerable importance in highly developed machines of this class which, among other functions, may be adapted to accumulateand indicate amounts and torecord the items indicated and the totals accumulated ona detail strip, an inserted sales-slip, and

- fer mechanism is designed to effect transchecks issued by the machine. Care must be taken to give the proper time for the accomplishment of each of these objects, of the parts being so operated during one complete rotation of the main drive or cam shaft. To accomplish this object the transfers simultaneously instead of-successively as is commonly done in the art, these transfers in the present case being accomplished after the-actuating members for the totalizer elements have imparted differential movement to the latter.

tions, projections on the elements partially set trip pawls carried on transfer frames.

Each trip pawl is so constructed as to pass into contact with the transfer'frame of next lower order than the transfer frame carrying the partially set or tripped pawl so that when this transfer frame of next lower order is rockedby a transfer bail to effect a transfer the transfer frame carrying the partially tripped pawl will also be rocked and thereby effect a transfer by a transfer. As the pinions pass from their nine to their zero positions the trip pawls are fully tripped and 1n this, position they are directly in the path of movement of the above mentioned transfer bail which, when rocked by the operating mechanism, engages the fully tripped pawls to rock the transfer frames carrying the fully tripped pawls and thereby also rock as above stated the transfer frames carrying the partially tripped pawls and connected by these partially tripped pawls to the transfer frames carrying the fully tripped pawls to effect all the required transfers at the same time.

Another object of this invention is to so construct the transfer mechanism that it maybe employed in machines-the differential mechanism of which is designed to turn the totalizer elements in a forwardly direction in item entering operations and in the reverse direction in a total taking operation in which the total on the totalizer is recorded on record material and indicated by the indicating mechanism. To efi'ect this.

object the transfer mechanism is adapted to be moved out of operative relationship with the totalizer pinions when the latter are reversely movedin a total taking operation.

With these and incidental objects in view,

the invention consists in certain novel features of construction and combinations of parts,

The purpose of filing this application in addition to the above mentioned copending application is to claim the transfer mecha- .nism in a separate application and only so much of the machine as is necessary to the understanding of the operation of the totalizer and its transfer mechanism will be here described. It is not intended, however, to limit the present invention to any particular form of accounting machine and the differential mechanism shown in the above drawings is used for illustrative purposes only,

The particular type of differential mecha- IllSm shown in the drawings -is fully disclosed in the above mentioned copending application, and for a detail description of this mechanism reference may be had thereto.

A. brief description of the differential mechanism will, however, be given here.

' The keyboard consists of a plurality of banks of keys 1 and one of these banks is shown in Fig. 1. The keys are slidably mounted in supporting frames 2 which in turn are supported in proper position in the machine by tie bars 3 and 4.; As is usual essee? in the art springs (not shown) coiled about the key shanks, normally retain the keys in undepressed position and if the keys are operated serve to restore them to their undepressed position near the end of the operation of the machine. Each key is provided with a laterally extending 'pin 6 passing through an opening 7 in the supporting frame 2 and across the forward edge 8 of a determining member 9 for the same'bank. The usual detents (not shown) are employed toretain the operated keys in depressed position until near the end of the operation of the machine. In addition to the usual amount keys a zero trip (notshown) below the bottom key in each bank is provided, as

with the particular mechanism employed it is necessary to prevent the driving mechanism from imparting a movement to the actuating members fora totalizer pinion of a denomination when no amount key inthe corresponding bank is depressed. The-zero I trip for each bank is normally held inoperative position but is moved out of operative position when any key in the corresponding bank is operated and is restored to normal position when the depressed key is released near the end of the operation of the machine. A pin 11 in each bank is carried on a lever (not shown) supporting the zero trip and the pin passes through an opening 271 in the key frame 2. The pin is normally in engagement with the forward edge 8 of the determining member 9 and is moved out of engagement with the determining member upon depression of the key in a manner described in the above mentioned copending application.

Referring further to Fig. 1, 12 indicates.

the main drive shaft, and the devices operated thereby are designed to be operated during one complete rotation of the drive shaft at each operation of the machine. A motor or other driving-means for the shaft is omitted from the drawings as such means forms no part of the invention. The shaft 12 carries rigid thereon a gear wheel 13 'meshing.with a gear wheel 14 loose on a stud 515. projecting from the right hand side frame of the machine. This latter gear wheel is provided with twice as many teeth as the gear Wheel 13 so that one rotation of the shaft 12 causes one-half rotation of the gear wheel 14.' The gear wheel 14 has a cam groove 16 formed in its face. I A roller 17 mounted centrally on an arm 18 pivotally mounted on a shaft 19 projects into the groove 16. Rigidlymounted on theshaft 19 is a gear wheel 21 having one-half as many I teeth. as the gear wheel 14 with which it meshes" s0 that uponeach one-half rotation of the gear wheel 14 the shaft 19 will be given one complete rotation. The upper end of the arm 18 has a link 20 pivoted. thereto,-the forward end of. the being pivoted by a pin 22 to the upper end of an arm 23 fast on a shaft 15 supported by the tion to normal position.

Fast to the shaft 15 are arms 26, one for each bank of keys-(Figs. 2 and 10). Each arm 26 near its outer end carries an arm 27 loosely mounted on a pin 28. Springs 29 which extend between pins 31 on the arms 26 and the lower end of latches 32 mounted on the arms 27 by the pins 33 tend to urge the upper arms of the latches forward but the latches and therefore the arms 27 are normally prevented from having a movement relative to the arms 26 by the engagement of lugs 35 on the latches with the upper edges of slots 37 formed in the arms 26. When the arms 26 are rocked counterclockwise (Figs. 1 and 2) rollers 38 carried on the upper ends of arms 27 move along the rear edges 39 (Fig. 1) of the differential determining arms 9 which are pivoted at their lower ends by sleeves 41 secured to the determining arms 9 and supported by cars 42 on the key frames 2. The edges 39 of the determining arms normally extend inclined across the path of movement of the rollers 38 and thus the rollers upon counter-clock.

Wise movement of-the driving arms 26 normally urge the determining arms 9 torock clockwise their full nine units of movement. The arms 27 are normally prevented from rocking counter-clockwise by engagement of the lugs 35 on the latches 32 with shoulders 36 formed in the slots 37. Latches 32 carry at their upper ends pins or rollers 44 (Fig. 2) to engage in an adding opera tion of the machine either the zero trip (not shown) or the inner ends of the keys 1 when the latter are in depressed position. From the above construction it follows that on counter-clockwise movement of the arms26 in an adding operation the rollers 38 .on the arms 27 rock the determining arms 9 clockwise until the pins 44 on the latches 32 engage the inner ends of the depressed keys which engagement results in the latches 32 rocking counter-clockwise whereupon the lugs 35 become disengaged from the shoulders .36, after which the continued counterclockwise movement of the arms 26 merely results in counter-clockwise rocking of'the arms 27.

The determinin arms 9 are provided with arcuate slots 48 Fig. 1) which, when the arms 9 are in their nine positions and therefore furthest from normal, are praca corresponding segment gearl 52 4 which is exactly concentric with the- ,bell crank in form and pivoted by a pin 53 on the forward end of the arm 26. The teeth-on each segment gear 52mesh with the teeth of a correspondin segment gear 55 loosely mounted on the roc shaft 15. Integral with each segment gear 55 but of greater radius is another segment gear 56 which is employed to actuate the corresponding totalizer pinion 47 after the pinions are thrown into engagement with these actuatingi segment gears.

32 are tripped. After the latches are tripped, however, and untiLthe rollers 51 reach the upper endsof the slots 48 the speed of rotation of the segment gears 52 which was but slight before the latches were tripped, is increased. In this way diflerential movement is imparted to the segment gears 55 and therefore to the actuating segment gears 56'for the totalizer during the entire upstroke of the arms 26.

' The indicators 46 (Fig. 1) are difi'erentially rotated on the upstroke of the arms 26 in accordance with the differential setting of the determining arms 9 by se ent gears 58 pivoted on a cross rod 59 be ow thekey frames2. The segment gears have slots 61 through which the rollers 51 on the segment there being one segmentgears 52 extend,

gear 58 for each denominational order rep resented. The slots 61 are curved at thelr forward edge in about the same way aS slots,

48-and are so shaped thatupon u movement of the rollers 51 as guided y the slots 48, the rollers, engage one side or the other of the slots 61 and thus differentially position the segment gears 58 directly from one position to another. The segment gears 58 have teeth62 meshing with segment racks 63 rigidly fastened to the sides of the 1ndi cator setting gears 64, which mesh wlth Pmions 65 integral with the indicators 46 and consequently cause the differential movement of the segment gears 58 to-be imparted to the indicators.

In order to aline the indicators 46in their set positions at the end of the upstroke of the arms 26,'the ears 64 are provided with alinin notches which are normally engaged y noses 68 of arms 69 rigidly mo nted on a shaft 71 which extends longitudinally ing concentric with the fixed pivot 59 of the segment gears to ermit movement of the latter. The shaft 71 is rocked to move the arms 69 out of and into engagement with the 'alining notches on the gears '64 by a cam the left hand side frame of the machine and shaft 88. Loosely mounted on the shaft 88 is a lever 89 which is bifurcated at its lower end (Fig. 6) and normally straddles a groove 74whichoperates an arm 75 fast on squared projection 91 (Fig. 8) on a selectthe shaft 71 through engagement of a roller ing bar 92 slidably carried in rectangular 76 on the arm in the cam groove.

The lever 106 is rocked to throw the totalizer into engagement with the-actuatingsegment gears 56 and from stationary plates 138 (Figs. 2 and 11). a a v a The totalizer pinions 47 (Figs. 1 and '2) are mounted on a tubular shaft 86which is by a cam groove 108 which is formed in the supported at its ends in arms 87 only one face of the disk'110 and, engaged by a roller of, which is "shown in the drawings. The 111 on a pitman-105 connected to the lever left hand arm 87 (not shown) is pivoted'on 106. This cam groove -1 08-is designed to rock the totalizer into engagement with the I actuating segment gears before the arms 26 begin their upstroke and maintainsthe engagement of the totalizer element with the segment gears only until after the arms 26 have completed their upstroke.

For the purpose of sliding the plate 92 so that the projection 91 will be in engage y ment with the levers 101 or 106, actuated the read and reset cams respectively, a lever 115 is provided (Figs. 6, 8 and 9). Projecting laterally from the lever 115 is a pin 116 passing into a slot 117 formed in the lower end of a link 118. The link (Fig. 1)

.at its upper end is pivoted by a pin 119 to an arm 120 rigidly mountedon a shaft 122 which is rocked by a total lever 123 also fast thereon. The rear end of the lever 115 (Fig.

9) carries a roller 124 which in each position of the lever plays in one of the three grooves 125, formed by the concentric ribs .126 on the face of a disk 127, during the rotation of the shaft 19 upon which the disk is rigidly mounted. Engagement of the roller 124 in the grooves 125 prevents displacement of the lever during the operation of the machine. The forward portion of the lever 115 is enlarged and the face of thisenlarged portion 128 is concentric with the pivot of the lever and has a cam groove 129 in which a roller 131 (Figs. 6 and 8) projecting laterally from the right hand end of the slide 92 projects. From this construction it is evident that upon ad ustment of the total lever from its normal add position to a read or reset position the selecting bar 92 will be slid to the left to render the adding cam 99 ineffective and render either the read or reset cam eflective as desired. A spring 132 restores the lever 115 and therefore the bar 92 to normal position at the end of the rotation of the shaft 19.

In a total taking operation the counterclockwise movement of the actuating segment gears 56 upon the upstroks of the arms 26 and after the totalizer has been thrown into engagement with the segment gears, effects clockwise movement of the totalizer pinions. This reverse movement of each totalizer pinion is adapted to be stopped when the latter reaches zero position by the engagement of a long tooth 135 on the pinion with the rearwardly extending arm 136 (Fig. 2) of a corresponding bell crank lever 137 adjacent each pinion and pivoted to one of the plates 138 (Fig. 11) which are loosely mounted on the rock shaft 15 and a shaft 139 to permit movement of the shafts without effecting the plates. The arm 136 adjacent each totalizer pinion carries a laterally projecting stud 140 which is in the same vertical plane as a lever 141 pivoted on the arm 26 by a pin 142. When the am 136 of bell crank lever 137 is rocked by engagewhen the lever 141 is rocked by the long.

tooth the lug 35 of the latch is thrown out of engagement with the shoulder 36 to permit rearward movement of the arm 27 during continued movement of the arm 26. The rear end of the lever 141 carries a projection 146 which prevents undue lateral displacement of the lever 141 as the lever is prevented from moving to one side by the engage ment of the projection 146 with an arm 147 integral with the arm 26 and to the other side by the engagement of the projection 146 with the head ofa pin 148 projecting from the free end of the arm 147.

To effect, in a total taking operation, the alinement of the actuating segment gears 56 in their set positions after the latches 32 have been tripped, arms 150 are provided with pins 151. The arms 150 are loosely mounted on the shaft 139 and carry lugs 152 normally in engagement with shoulders 153 formed on the downwardly extendin arms 154 of the bell crank levers 137. prings 155 connecting the arms 150 with the bell crank levers 137 normally maintain the engagement of the lugs 152 with the shoulders 153. When the bell crank levers 137 are rocked by the long teeth 135 on their adjacent pinions the shoulders 153 are carried out of engagement with the lugs 152 on the arms 150. Then the arms are rocked clockwise (Fig. 2) by the springs 155 and the lugs 152 are moved into engagement with the second shoulders 159 on the arms 154 so that the studs 151 on the arms 150 mayfpass between the teeth of the actuating segment gears and in this way lock the latter from further movement. After the arms 26 come to rest at the end of their upward stroke, the arms 150 are rocked back to normal posltion so that the actuated segment gears may be returned to zero position on the return movement of the arms 26. To this end arms 161 fast on the shaft 139 and beside the arms 150, are rocked counter-clockwise to engage studs 162 on the arms 150, so that when the arms are carried back to normal pos1t1on the springs 155 will pull the bell crank levers 137 to normal position. The shaft-l39 1S rocked to lower the arms 161 at the proper time by means of abox cam 165 (Fig.4). A pitman 166 has a roller 167 engaging in a groove 168 of the box cam 165 and the lower end of the-pitman is pivotally connected to an arm 169 fast to the shaft 139 so that near the end of the rotation of the cam 165 the pitman 166 is reciprocated to rock theshaft 139. Simultaneously with the restoration of the arms .150 to normal unlocking position the tripping levers 1.41 are restored to normal position by springs 170 connected by pins 171 to the levers and by pins 31 to the arms 26.

, The transfer mechanism, which is shown in Figs. 2 and 3, includes a frame, for each I the upper end of the arm 177 j of each transfer frame by a pinion 182 and this pawl isnormally in the plane of the totalizer-wheel of next lower denomination. Each trip pawl 181 has a nose 183 on its lower portion and the nose is normally in engagement with the foremost of three notches 184 formed on the upper edge of an arm 185 loosely mounted on the shaft 175 between the transfer frames. This arrangement is normally maintained by a spring 187 which is-under pivotal center 182 by the long tooth 190 and the spring 187 raises the arm 184 so that the Y hand side of thearm 176 of tension between an extension 188 of the arm 185 and a projection 180 of the trip pawl 181. The'forward end of each trip,pawl is provided with a notch 189 which is engaged by a long tooth 190 on the adjacent totalizer pinion when the pinion passes from its eight to its nine ,position. Thisengagement rocks the pawl181 clockwise without affecting the transfer frame supporting the rocked pawl but the spring 187 raises the arm 185 so that the second of the notches 184 in the arm 185 will engage the nose 183 of the pawl. The pawl on the left in Fig. 3 is shown in this position. In this position the upper inclin'e d edge 191on the rear end ofthe lower portlon of the trip pawl 181*passes into engagement with the rear edge of a horizontal lug 5192 projecting laterally from the left the next lower If the pinion passes osition the trip urther about its order transfer frame. from its nine to its zero pawl 181 is rocked still nose 183 of the; pawl will engage the third.

, notch in the arm 185 and th1s is the position that the middle trip pawl in Fig. 3 of the drawings has assumed. In this position of the pawl181 the upper inclined edge 191 of the pawl is in engagement with the rear edge of a long horizontalbar 195 of a transfer bail. I

The bail comprising the horizontal bar 195 integral with arms 196 fast on theshaft 175, is rocked counter-clockwise (Fig. 2)

before the totalizer in an add operation of the machine is restored to its normal po- 'erated transfer frames come to rest for a short. time at the end of their clockwise movement and the add cam 99 then rocks sition in engagement with the teeth 179 of the transfer frames.- This isdue to the angle at which the extensions 183 of the pawls-181 coiiperate with the notches in the arms 185. The cam for rocking the transfer bail is so shaped that the bail and the opthe totalizer back into normal engagement with the teeth 179 of the transfer frames.

As the bail is rocked back to normal position the operated transfer frames are also restored to normal position and the teeth 17 9 of the frames being in engagement with the corresponding totalizer pinions cause the pinions to be'moved therequired one step. The transfer frames are restored to normal position to effect these transfers by springs 200. There is one spring for each transfer frame and each spring passes about the tubular shaft 175 and at one end is seated in an opening 201 in the shaft, the other end being bent to engage the forward edge of the horizontal bar 178 of the transfer frame. V

'If one pinion, for example the units pin ion, is moved from its nine to its zero position or beyond by its actuating segment gear, the associated trip pawl 181 is fully tri pod and if the pinion of the next higher or er, that is, the tens pinion, is at its nine position'i t is-evident that when one is added on the tens pinion,by the carrying opera-- tion from the units p1n1on, a carrying operation from the tens pinion to the pinion of. next higher order, that is, the hundreds.

of eflecting a transfer by a transfer clearer,

assumethat 133 stands on the totalizer and 69 is to be added. Atjthe end of the opera tion the position of the totalizer pinions .1110 pinion, is necessary. To make the method a be moved nine steps by its actuator through 0 to its 2 position and, of course, '1 should be carried by the transfer mechanism, as above described, to the tens pinion; The tens pinion, however, is moved six steps by its actuator to its 9 position and the carrying of 1 from the units pinion will turn the tens pinion to the 0 position sothat it will benecessary to carry l from the tens pinion to the hundreds pinionvin orderthat the position of the totalizer. pin-- ions will represent the correct total. This operation of effecting a transfer by a transthrown into engagement fer is accomplished through the above described pawls 181 and the projections 192 on the transfer frames. It has been stated that when a pinion passes from its eight to its nine position the adjacent trip pawl 181 is rocked about its pivot and the spring 187 raises the arm '185 to the right of the transfer frame supporting the pawl so that the middle notch of the arm 185 engages the nose 183 of the trip pawl and the inclined edge 191 ofthe pawl passes to the rear of the lug 192 on the arm 176 of the next lower order. It can therefore be seen that when a transfer frame is rocked by the transfer bail 195 engaging thefully tripped pawl carried by the frame, the lug l92 on the arm 176 of the frame will engage the pawl on the transfer frame of next higher order if the pawl is only partially tripped and, rock the higher order frame to effect a transfer. In this way a transfer by a transfer is effected and all the transfers are effected simultaneously. The deep notches 206 formed between the upper and lower portions of the trip pawls 181 are provided to prevent engagement of the pawls, when they are moved rearward by the rocking of the transfer frames carrying them, with the forward edges of the lugs 192 on the transfer frames of next lower denominations. L

The cam and connections for rocking the transfer bail at the proper time are-shown in Fig. 5. An arm 210 is fast on the hollow shaft 175 and the upper end of the arm is connected by a pin 211 to a pitman 212. The pitman at its rear end is forked over the shaft 19 and carries an anti-friction roller 213 playing in a cam groove 214 formed in the face of a disk 215 fast on the shaft'19. The cam groove is so designed that the pitman 212 is given a rearward movement to rock the shaft 175 and therefore the bail rigid therewith in a counterclockwise direction before the totalizer is rocked out of engagement with its actuating segment gears 56. After the totalizer is with the teeth 179 on the transfer frames the bail is restored by the cam 214 to normal position to permit the springs 200 above described to restore the transfer frames to normal position for the purpose of effecting transfers.

After the transfer frames have been rocked back to normal position by the springs 200 to effect transfers, lugs 217 (Figs. 2 and 3) on the shaft 19 which ro-' tates in a clockwise direction, engage the upper iends of the projections 188 of the arms 185 and rock these arms counter-clockwise about the tubular shaft 175 without effecting the transfer frames so that the noses 183 of the trip pawls which were tripped are restored under the influence of the springs-187 to their normal position in corresponding actuating segment gear 56 when the pinion passes from its one to its zero position in a total taking operation of the machine, and that part of the long tooth 190 which. projects from the outer circle of each pinion and is employed to engage the adjacent trip pawl 181 in an adding operation is formed on the left side of the tooth which isopposite the pawl as the pinion passes from its nine .to its zero position in an adding operation so that the arms 136 will only be operated by the'long teeth 135 and the trip pawls 181 only by the long teeth 190. The teeth of the'segmental actuating gear 56 are long enough to permit the long teeth 135 and 190 of the totalizer pinion to engage between the same, the remaining teeth of the totalizer pinions being shorter than the teeth of the actuating segment.

In order to prevent the teeth 190 of the totalizer pinions from engaging the pawls 181 when the pinions are turned clockwise in a total taking operation, the shaft 19 is provided with cam projections or flanges 220 which, while the pinions are being turned to zero on the upstroke of the'driving arms 26 in a total taking operation, engage the rear ends of arms 176 of'the transfer frames and thereby rock the transfer frames counter-clockwise so that the trip pawls are taken out of the path of movement of the long teeth 190. The circular surfaces of these cam projections 220 are concentric with the circumference of the shaft and subtend an angle of about 60 so that they hold the transfer frames in their rocked positions during the entire upstroke of the driving arms 26 and pass out of engagement with the arms 176 of the transfer frames before the return movement of the actuating seg ment gears to normal position is begun. Of course in an adding operation the transfer ,frames are rocked by the cam projections 220 and in such an operation the totallzer tion does not effect a change in the positions of the totalizer pinions.

As the transfer frames and therefore the trip pawls 181 are returned to normal position when the cam projections 220 pass out of engagement with the arms 176 of the transfer frames, it is evident that the pawls are in the path'ofmovement of the long teeth 190 when the totalizers are turned back to their original position upon return of the actuating segment gears to normal position in read operations.v It is obvious that it is necessary to prevent the actuation of the transfe'r frames which have been prepared for effecting transfers during such return movement of the actuatingsegment gears from affecting the totalizer pinions, as otherwise the totalizer would have one added 7 on each pinion if the trip pawl 181 adjacent the pinion of next lower denomination has been tripped while the actuating segment gears are being returned to their normal position. To this end the readcam 103 is so timed that the totalizer is not rocked out of mesh with the actuating segment gears until after the transfer bail is operated by its cam- 214 so that when the transfer frames are rocked back to normal position by their springs 200 the teeth 179 of the transfer" frames are not in engagement with the pinions and therefore the actuation of the transfer frames does not operate the pinions.

Operation.-

To recapitulate, the operation of the transfer mechanism which is claimed herein may be briefly described. During the rotation of the totalizer pinions as they are moved from their eight to their nine posltions by their actuating segment gears, the

long teeth 190 on the pinions engage the notches 189. in the forward ends ofthe trip pawls 181 and'rock the latter so that the second notches 184' in the pivoted arms 185 are raised by the springs "187 into engagement with the noses 183 of the partially tripped pawls. In this manner the upper inclined edges 191' on the lower portions of the partially tripped pawls 181 are moved to .the

\ rear of the lugs 192 on the arms 176 of the transfer frames which have the teeth 179 normally engaging the pinions partially tripping the pawls 181.

As the totalizer pinions pass from their nine to their zero positions the trip pawls 181 are fully tripped by the engagement of the long teeth 190 and in this position of the pawls'the springs 187 .raise the arms 185 so that the noses 183 of the fully tripped pawls engage the rearmost notches of the arms 185 and the upper inclined edges 191 of the pawls are then in engagement with the rear edge of the bar .195 of the transfer bail.

After the driving arms 26 and the actuating segment gears 56 have been restored to normal position and before the totalizer, is rocked out of engagement with the actuating segment gears and into normal engagement with the teeth 179 of the transfer frames, the transferbail is rocked-counterclockwise (Fig. 2) by the cam 214 through the medium of the pitman 212 and the arm 210 which is fast to the tubular shaft 175 upon which the transfer frames are loosely mounted. When the bail is so rocked counter-clockwise it' engages the upper inclined edges 1910f all the fully tripped pawls 181 and in this Way rocks the transfer frames carrying the fully tripped pawls ina counter-clockwise direction. After the totalizer w elements have been carried out of engagement with their actuating segment'gears and tuatingsegment gear the transfer frame of the pinion of next higher order than the first mentioned pinion would be -moved simultaneously with the movement of the transfer frame of the" first mentioned pin ion upon operation of the transfer bail through the engagement of the lug 192 on the transfer frame moving the first m'ention'edpinion one step with 'the inclined edge 191 of the trip pawladjacentthis first mentioned pinion. It can therefore be seen that when the transfer frames have been fully prepared to effect transfers by being coupled directly to the transfer bail through the trip pawls 181, the transfer frames coupled to the fully prepared transfer frames by the partially tripped pawls 181 are rocked simultaneously to effect transfers by transfers. I

For example, if the totalizer pinions are all standingat 8 and one isadded in. each de nominational order, as the pinions are advanced to their 9 positions the long'teeth 190 .of the pinions will engage the transfer trip pawls 181 and move them one step to engage their extensions 183 with the second notches in the arms 185.

A This movement of the transfer trip pawls will carry the inclined edges 191 of the-extensions of the trip pawls into the path of the lugs- 192 on the arms 17 6 of the next lower order transfer frames.

The first pawl from the left-in Fig. 3 is.

shown in this position. If one be now added on the. units totalizer pinion the pinion will be advanced from 9 to'O and its long tooth will give a second stepof movement to its transfer trip pawl 181' and move the pawl rearward to engage the thirdnotch in the arm 185. This position is occupied by the second pawl from the left in Fig. 3. When in engagement with the third notch of the arm 185 the inelined edge 191' of the units trip pawl 181 will beheld up in the path of the invariably moved transfer operating bar the-invariably moved transfer bar 195 and that the higher order transfer rock frames will all be connected for operation because of the fact that the inclined edges. 191 of their pawls 181 will be in the paths of the lugs of the next lower order transfer frames.

clined edge 191 of the unitspawl 181 to rock the transfer frame intermediate the units and tens pinions ready to turn the tens pinion one division and at the same time the lugs v192 on the higher ordertransfer frames will act upon the edges 191 of the 'pawls 181 and rock said frames one step'rea'dy' to add one on then totalizer pinions when the transfer bar 195 is swung backfto its first position and the frames operated by the I transfer springs 200. In other words, movement ofthe totalizer pinions from their 8 to their 9 positions adjusts the pawls 181 to form a positive bond between the adjacent transfer rockgframesand if the lowest order franie is then rocked by means of the transfer b'a'il' 195 all of thetransfer frames will.

on account of said bond be simultaneously rocked. The latchingarms 185 are \so shaped and coiiperate with the transfer trip pawls 181'in such a way that the transfer rockframes w ll have substantially the same extent of movement regardless of whether the are rocked directly by the operating 176 of said frames.

bai 195 *or through the connection afforded by the pawls 181 and lugs 192 on the arms I-t is, pf course, clear that if a totalizer pinion 1s notat the 9 position/no bond vis formed at. that point between the adjacent transfer rock frames so that the frames either above or below that point maybe rocked without'one affecting the other. On the other hand, a bond can have been formed between two adjacent rock frames bllt'lf the higher order frame ofthe' two is rocked by means of the transfer operating ball 195' the lower order frame of the two will not be rocked or in any way 'a-fiected.

For example, if the units andtens pinions both stand at 8 and v1 .isadded on'each .Jof'

them, as they reach the 9 positionthe transfer trip paw e181 will be given asingie' step of movement and carrying the inclined =port1on 181 of the extension on the pawl actu--.- ated by the tens pinion into the path'of the lug 192; on the arm 176 of the next lower order frame. If, now, onebe added on the f movementto carry the inclined .portion191 'of its extenslon '1n the path of the operating tens pinion the tens-hundreds-transfer trip pawl 181' wlll be. gIVBILBH additionalstep of bail.19 5. Then'when the bail is rocked the tens-hundreds transfer frame willbe'rocked,

but the units-tens. frame will remain station-v pivoted members to combination with elements; of transf r 'devlces there or; pivary because'of the clearance 206 in the pawl 181 associated with the tens wheel. That is to say, when the tens-hundreds transfer frame is rocked the-tens trip pawl 181 will merely move idly past the lug 192 on the units-tens transfer frame. At the end of the operation the tens pawl 181 will, of course, be fully restored to its nuntripped positionbut when the units pawl 181 is released it will only return to its half tripped position, being stopped in the half tripped position by coming in contact with the long tooth 190 on the .units wheel which, it should'be remembered, still remains at the ,9 position. If the units pinion should at the next operation be carried to or through 0, the units-tens transfer frame will then-be operatively connected to the invariably moved transfer operating bail 195 ready to turn in the transfer.
